Bronze and brass are metal alloys, or a mixture of two different metals. The main difference between bronze and brass, therefore, is found in the mixture of metals used to form them. Brass is formed by combining copper with zinc, while bronze is formed by combining copper mostly with tin and sometimes with other elements, such as manganese, phosphorus, silicon or aluminum.Continue Reading
Subjecting alloys to a chemical test is the surest way to distinguish one from the other. However, bronze and brass can also be differentiated through their physical properties. Bronze has a pinkish hue in its raw state; however, it is rarely seen in this state. It is typically described as having a reddish brown color. Brass, on the other hand, has a muted yellow color that is somewhat similar to gold but duller.
Bronze is hard and brittle and typically melts at 950 centigrade. It is resistant to corrosion, particularly salt water corrosion, and metal fatigue. Bronze is also a better conductor of heat and electricity than most metals. Brass is very malleable, easily stamped and deep drawn. It is not as hard as steel, but it has good strength and fair electrical conductivity. Brass can also be resistant to corrosion when combined with iron, manganese, aluminum and silicon.
Because of its physical properties, bronze is often used in cast bronze sculptures, boat and hip fittings, propellers, door and window frames, rails, bearings, clips, electrical connectors and bells. Brass, on the other hand, is widely used for decorative items, gears, locks, doorknobs, ammunition, electronics and fittings that are used to negate sparks.Learn more about Chemistry
Metalloids are used very commonly in solid-state electronics, as components of alloys in metal objects, in glass and in flame- and heat-resistant objects. Metalloids in their pure forms are too brittle to be used in tools or in structural applications.Full Answer >
Metallurgy is the study of metals and metal mixtures, called alloys. Ancient metallurgy was based mainly on folklore and trial and error. Modern metallurgy is based in science and essential for producing the metals on which modern-day society depends.Full Answer >
The smell (or flavor) of natural vanilla is a mixture of about 200 different compounds. However, vanillin is the most prominent one, and has the chemical formula C8H8O3.Full Answer >
Bronze is an alloy made of 88 percent copper and 12 percent tin. Other metals, such as aluminum, zinc, lead and silicon, are added to it frequently. It is malleable, ductile, lustrous, hard, golden brown in color, and a good conductor of heat and electricity.Full Answer >
